The downside of running low of free space

This isn't really installation and configuration but it was related to my protection domain snapshot issue. So, when I ran low on free space, the metadata increased becasue there were still tons of blocks out there to keep track of. So, this combination of low space and threshold breaking metasada size exceeds the preconfigured (metadata) size limit before kicking off automation actions. I don't really understand these failsafe actions fully but both inline compression and deduplication fingerprinting (I use only performance tier dedup but my true love is compression) are disabled. I am not so sure about compression but I can see deduplication fingerprinting adding to metadata. The kicker, to me, is that space conservation via deduplication and compression is more important when I am low on space. The recovery from these automatic actions is to free space then call support to re-enable the disabled features. I am waiting for an answer why they do not automatically re-enable

Protection Domain Local Snapshots and my mistakes

One of the mistakes I made recently was not understanding my daily snapshots, retention and expiration well enough when I created protection domain to keep local snapshots. First, I took a shortcut to creating daily snapshots by selecting Repeat Weekly with every day selected. The docs are a bit light on details so I assumed this would be treated like a daily snapshot. This can casue a problem with many snapshots to keep. I selected 7 so I would have a running weeks worth. Actually, it keeps 7 weeks worth of weekly/daily snapshots. When my free space decrease to a warning state then critical state, I started looking at VM usage but found it increased only a couple TB which meant I was missing about 40TB! While it wasn't clear the snapshots were consuming massive storage, it was clear it was not what I planned. So, I deleted a bunch of snapshots after changing to daily snapshots and keeping the last 14. This helped free a lot of space but there was still some space miss

is there a way to Remove scsi controller beyond what is available in prism.

I can remove the controller using 'virsh edit' or through virt-manager connected to the host, but those changes do not persist, and Acropolis adds the scsi controller back in when the VM is started.Is there any supported way to do edit VM properties beyond what is exposed in Prism and to have the changes persist?

Datacenter refresh with DR, single or dual socket?

Hi guys, i'm a potential new Nutanix customer here in Italy ! Actually 43 VM's 6.5TB, 20% CPU average use (6X Xeon 5680 CPU) 400 write/iops average during 24hours and 3000 of peak. The goal is two sites in stretched cluster with sync writes, connected with 2x1Gbs fiber and upgradable to 10Gbs if it is necessary to this project. Actually we have 6 cpu vmware ent. license, 6 cpu Veeam ent.plus license and 6 CPU Microsoft OEM License that i need to rebuy with the new hardware. One key point is the Oracle VM, we've 6 cpu standard one license and Oracle want to license all Vsphere cluster, we discussed with Oracle Italy and with two legals...and that's it! Our partner send me two projects variant: 1) 6 nodes dual socket, 3 per site with 12 Haswell v3 cpu 72 cores in global. 2) 6 nodes single socket, 3 per site with 6 Ivy bridge v2 CPU 60 cores in global. With the number 1 i need to create and buy a dedicated vsphere cluster to run Oracle across 2 of 6 node, I can also use this second cl

The question is how do change the IP addresses for nutanix equipment when moved to the secondary site. What other option that i can consider? Hypervisor will be VMware 5.5 Update 2.

3 node cluster design for 6000 series nodes

I'm putting together a design for a 3 node cluster with the 6000 series nodes. The first block is 6235-G4, the second block, I'm a bit confused. I could get another identicle block with 1 node ( 6135-G4), but there is also the option of getting a 6135C, which is single socket, less RAM, smaller SSD and crappier CPU. It's cheaper and will make the min 3 node cluster, but I'm wondering what kind of performance hit it will have for the overall solution. Am I better off getting a 6135-G4 and being done with it?

NX-6260 ( NX-6060 - Part 422-NX-6260 ) Power Specifications

Hello - Can someone reply with the complete power specifications for the Nutanix NX-6260 ( NX-6060 )? I know these have dual power supplies. Please provide the following at minimum: 1.) Voltage of each power supply - I think these are 208V Single Phase 2.) Amps per power supply 3.) Watts per powerr supply 4.) Power Cable Ends - Please confirm - I think these are C13/C14 for each power supply. We do not yet have the boxes so I need to prepare for the power requirements of these devices. I am looking at two of the Tripp-Lite PDU Basic 208V/240V 30A C13 10 Outlet L6-30P Horizontal 1U - MFG Part #: PDUH30HV Also wondering what others are using. Thank You. Sam

Protection Domain Warnings

I have three protection domains, all containing VM's. All three have schedules set and I can see that local snapshots are being made. I have restored machines with no issues. All seems well, but I am getting "Backup Schedule" health warnings on all three PD's. [b][i]Causes of failure[/i][/b][i]No backup schedule exists for protection domain protecting some entities.[/i] [i]Backup schedule exists for protection domain not protecting any entity.[/i] Neither of the above suggestions is true. I can't seem to get this one to resolve. Is this a bug or is there something here I am missing?

Active Directory configuration fails with "Directory config name is invalid"

I cannot seem to get Active Directory authentication configured and cannot figure out why. After following the directions in the support article "Configuring Authentication" I receive the message "Directory config name is invalid". Here is what I have tried: using the IP rather than the host name, turning off the firewall on the DC, using a different AD host, trying different ports (i.e. 389 and 3268), trying a different browser (firefox and IE), specifying the full directory path (/ou=,dc=,dc=) - nothing seems to work. I just keep getting the error message "Directory config name is invalid". I can ping the DC host from the CVM using the FQDN; firewall issues have been ruled out by turning off the firewall; the LDAP url is typed correctly. My thought is that this feature simply isn't working correctly on 4.1.3. Has anyone else experienced problems getting AD configured properly?
